Is it better to widen my 20x9 or 20x10 wheels and how wide can I go without modifying my bump stops?

If you want to move the 10's to the front, then the 9's would need to be widened. I believe 11.5" is what most guys have found to work for full travel of the axle.
I did 12" and have not modded anything on my car except to remove the Eibach rear shock boots and the rear brake ducts that were installed on my car at Shelby Las Vegas. When I raise my car on a 2-post lift, it is a two step process, but to me it is worth it, I wanted the wider size Alcoa's on the rear and also no cutting on my car.
I have had no issues with bump stop contact for over two years now.......
^^^10's on the front and 9's widened to 12".

What brand tire do you have on that car, what size? Any rubbing at all under real hard cornering? I've got the griggs stuff in my car and it's pretty low, but with the Watts link. I've really wanted to widen the wheels as you have but am afraid to pull the trigger without more positive feedback. I will be driving this thing pretty aggressively and don't want to have any issues.

I have 2 full sets of alcoas so I'm not consernd about putting 10's up front I wasn't sure if the 9's had a different offset from the 10's I think I'm going to end up widening them to 11-1/2 to be safe n
Would it be safe to say that I could run 11.5 Alcoas on the rear and maintain full suspension travel without having to modify the bump stop or remove the dust boots? What tires size and brand are you guys with 11.5s running without interference issues?

With pics, 20x9, 20x11 (widened 9s) with Nitto rubber, no issues, could have easily went 11.5-12" based on the inner fender clearance I can see from laying under the car on ground level.

True, I ordered zombeast's bumpstop relocation in anticipation of that and maybe using 18x12s and 345s for the strip down the road. At this point I'm thankful they're not needed, but it will be lowered soon and I might just do it while we're in there doing the suspension mods.
Your posts have been very helpful while I've been researching, car looks great with those wide meats!

^^^^Yes, this is what I have heard. 11.5 should be fine, but that also limits the tire width to 305-315 unless you don't mind a big bulge out past the fender lip.

I put my 201x10's up front and widened the 20x9's to 11.5". NO, you WILL NOT get full travel with an 11.5" Alcoa without modifying the bump stop bracket. The inner wheel will contact the bumpstop bracket when you jack up the car unless you do like Robert M suggests by using two jacks or jack it up by the pumpkin. Additionally, you will only get about 1/4" tire bulge with a 315 series R888. Read through my thread below for more info. Hope this helps.

Other than adjustable FRPP panhard bar, I run that tire on an 11" Alcoa and made no other mods.
11.5" isn't necessary and there isn't much bulge on the 11". I do think if I ordered the Alcoas myself, I probably would have gone 11.5" as its same price.
